Are you breastfeeding?
I've learnt over the years that my libido is ruled entirely by my hormone levels at any given time. I spent twenty years on some hormonal treatment or other for endometriosis. One of them put me into temporary menopause and my libido vanished for several years - and it wasn't just not wanting sex, just like you I couldn't stand to be touched at all. It was horrendous all round.
In the end I came off all hormones and it took about six months for things to improve. After I had my twins I pumped for seven months. Again, it's taken about six months of natural cycles for it to return. It's still a bit all or nothing (we were having sex every day then it went away again completely and a couple of days later my period started so again it seems to be hormonal).
I completely understand how distressing it is, but take it from me - don't go along with it to make him happy if you feel like you can't even stand to be touched or kissed. That will only lead to very negative feelings towards your husband even if he's not aware you don't want it. It will make things worse.
This will get better, your body just needs to adjust. You say you feel touched out so I'm guessing you may still be bfing. Obviously not everyone reacts to hormones during pregnancy and bfing this way, but there are lot as of women who do. Bfing is stopping them from ovulating and keeping their body in a certain hormonal state. I think it may be an evolutionary thing, to ensure you focus on the baby you have while they're still reliant on you so you won't have another, but that's just speculation on my part.
I promise there's light at the end of the tunnel. It will pass. I was starting to think I was in for more years of no intimacy but honestly when it improves it's like a light switch going on.
I should say it did come back once before, about 3 months after I stopped pumping but vanished again after 48 hours. It does feel to me like when my hormones reach a certain level it flicks the switch and when they drop it turns it off again. Sounds bizarre but that seems to be how it works, and I go from flinching any time I'm touched to wanting sex all the time, just like that.
Hang in there x
